Belt known that I, ANToNro TnoiANo, a

"Washington, in the District `of Columbia, have invented new and useful Improvements in Resilient Heels, of which the following-.is

a specilication. l.

The object of my present invention is the provision of. a resilient heel of such construction that the nail holes in the heel will be automatically closed after the driving of the attaching nails so as to exclude from within the heel dust, dirt and the like; the said construction also being of such character as to contribute to the neat iit of the resilient heel to the leather heel lifts.

To the attainment of the foregoing, the invention consists in the improvement as hereinafter described and definitely claimed.

In the accompanying drawings, forming part of this specification a Figure l is a top plan view showing a resilent heel made in accordance with my invention.

Figure l"L is a front edge elevation of the same.

Figure 2 is an inverted plan view of the said heel.

lFigure 3 is a View showing the resilient heel in cross section as properly arranged relatively to a leather heel and precedent to the attachment of the resilient heel to the leather heel.

Figure 4 is a similar view showing the resilient heel attached to the leather heel lifts.

Figures 5 and 6 are views of a straight or flat resilient heel constructed in accordance with my invention.

Figure 7 is a top plan view of another modified resilient heel constructed in accordance with my invention.

Similar numerals designate corresponding parts in Figures l to 4 to which reference will first beV made.

At its upper side my. novel resilient heel is characterized by a central portion 2, and' the underside of a ,heel lift the upper forward corner 5 of the resilient heel will be crowded or fitted tightly against the underside of the heel lift with a view to averting the entrance of dust between theresilient Specification of Lettersilatent.

' heel and thevopposed leather lift. It will also be understood by comparison of Figures l' and 3 that the upper side of the resilient heel l is generally concave, and is provided with a plurality of recesses 6in the bottoms of which are narrow radial grooves 7. At

the underside of the resilient heel l which underside is'generallycon'vex are provided protuberances. The said protuberances 8 are coincident with the recesses 6, Figures 2, 3 and 4, and it will also be noted that the protuberances 6 are of less diameter than the recesses 6. Extending upwardly from the undersides of the protuberances 8 and centrally thereof are nail holes 9 which are coincident with apertures in metallic reinforcing or anchor plates l0 that are embedded in the heel l.

In applying my novel resilient heel to a leather heel indicated by 1l, nails 12 are driven through the apertures 9 to the position shown in Figurev 4, with the result 'that the protuberances 8 will be contracted and the outer ends of the apertures 9 will be and so that after application the underside of the resilient heel will be practically imperforate and therefore calculated to last longer than those resilient heels that are apertured at their undersides. It will be understood in this connection that the nailing of the resilient heel l to the leather heel l1 will be attended by the straightening of the resilient heel'as shown in iFigure 4 so that the edges of the resilient heel and leather heel will be liush and a finished job produced. It will also be understood that when the recesses 6 are crowded againstthe underside of the leather heel 1l the said recesses 6 will give rise to a suction action which will have the effect of holding the resilient heel snug against the underside of the leather heel 11 with the result that the resilient heel will be retained in the straight state as shown in Figure 4 more perfectly than would be the case were the nails l2 alone depended upon to perform such function. At this time the protuberances 8, according to the size thereof, will either `be flush with the under surface of the heel or else will project but a slight distance from said surface. l

The resilient heel la as shown in Figures 5 and 6 is similar to the construction shown in Figures l to 4 with the exception that the resilient heel 11L is a straight or `flat heel having normally straight or fiat lovver andu erside's."v 1

In igure 7 I illustrate the upper side Aof a concave-convex resilient heel 1"' 'which lacks the protuberances 8 and recesses 6, buty isprov'ided at its upper side With'a central portion 2, a marginal inclined portion' and comparatively lon and more gradual inclinations 4 at the orward ends ofthe inclination 3, so that when the'said heelis applied to a leather heel the'upper forward corner 5 thereof will be enabled lsusceptible ofbeing inexpensively produced when made in large quantities. Having described my invention, what I claim and desire to secure by Letters- Pat entfiszi- A resilient heel having recesses in its vupper side and coincident protuberances at its underside and alsohaving nail hole's extending upvvardly through 'the protuberances and so constructed and arranged that when the driving home of nails the said holes Will be closed.l l

In testimony whereof I aflix my signature.
